File Name Variables
File name variables designate a data file and file path. File name variables are used in the SCPI
command syntax whenever files are accessed. The name of the file is always required, but the file
path can sometimes be optional or be designated using different formats. The following table shows
these different file path formats:
Formats 2–4 offer programming flexibility and are equivalent. Format 1 can only be used with SCPI
commands that imply the path name as part of the command syntax. Typically, SCPI load commands
that access user- data files do not need to have a file path designated.
See Table 1- 4 on page 15 for information on file types and directories.
NOTE The maximum length for a file name is 23 characters, excluding the file path.
Example Using Format 1
:CORR:FLAT:LOAD "FLAT_DATA"
The preceding example loads user- flatness data from a file called FLAT_DATA located in the USERFLAT
directory. No file path is needed as the command syntax implies the directory where the file is
located.
Example Using Format 2
:MEM:COPY "IQ_DATA@SNVWFM","Test_DATA@WFM1"
The preceding example copies a file named IQ_DATA located in the WAVEFORM directory to a file
named Test_DATA in volatile waveform memory (BBG).
Example Using Format 3
:MEM:COPY "SNVWFM:IQ_DATA","WFM1:Test_DATA"
The preceding example copies a file named IQ_DATA located in the WAVEFORM directory to a file
named Test_DATA in volatile waveform memory (BBG).
Format File Name Variable Example
Format 1 "<file name>" "Test_Data"
Format 2 "<file name@msus>"
"Test_Data@SEQ"
a
a.Included for backwards compatibility. Not a recommended syntax.
Format 3 "<msus:file name>" "SEQ:Test_Data"
Format 4 "</user/directory/file name>" "/USER/SEQ/Test_Data"
